Comparative evaluation of Schmidt hammer test procedures for prediction of rocks strength [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2018
Uniaxial compressive and Brazilian tensile strengths (UCS and BTS) of rocks are considered important properties in the design of most the geotechnical projects that interact with rock such as slope stability and underground excavation.

Calibration and Reliability of the Rebound (Schmidt) Hammer Test [PDF]

open access: yesCivil Engineering and Architecture, 2013
One of the most widely spread techniques to estimate the compressive strength of concrete is the rebound hammer test, also known as Schmidt Hammer test. In spite of a large number of scientific works trying to calibrate the test, to identify the parameters affecting its results and to estimate its reliability, the original Schmidt curve is still ...

Application of the Schmidt hammer in the relative-age dating of rockfall deposits in the Belvedere Glacier Valley

open access: yesActa Universitatis Carolinae Geographica
The Schmidt hammer is a cost-effective tool for both relative- and absolute-age dating of rocks (the latter in connection with previously absolutely dated surfaces).

A comparative study on the development of hybrid SSA-RF and PSO-RF models for predicting the uniaxial compressive strength of rocks

open access: yesCase Studies in Construction Materials, 2023
In the field of rock engineering, uniaxial compressive strength (UCS) is a crucial mechanical parameter that cannot be ignored. Due to the difficulty in obtaining high-quality rock core samples in some projects, it is essential to develop a reliable UCS ...

Time-resolved fuel injector flow characterisation based on 3D laser Doppler vibrometry [PDF]

open access: yes, 2014
In order to enable investigations of the fuel flow inside unmodified injectors, we have developed a new experimental approach to measure time-resolved vibration spectra of diesel nozzles using a three dimensional laser vibrometer.

How does a cadaver model work for testing ultrasound diagnostic capability for rheumatic-like tendon damage? [PDF]

open access: yes, 2016
To establish whether a cadaver model can serve as an effective surrogate for the detection of tendon damage characteristic of rheumatoid arthritis (RA). In addition, we evaluated intraobserver and interobserver agreement in the grading of RA-like tendon ...
